Sexual [Meta]-Preferences

Friday, 20 May 2022

As I noted in an earlier 'blog entry, I use the words choice and choose simply to refer to selection; and, when I say that someone prefers X to Y, I mean that if given a set of mutually exclusive options that include X and Y then Y will never be selected. Some people try to mean something else by one or both of these terms. In the case of choose, they seldom if ever explain what that something might be. R[obert] Duncan Luce proposed to define preference in terms of probability of selection, rather than in an absolute manner as do I; that difference won't bear meaningfully upon what I have to say here.

One might have preferences about one's preferences. For example, preferring-not-to-prefer simultaneously X to Y, Y to Z, and Z to X for any X, Y, and Z. But note that making choices based upon the preferences that one has is different from choosing to have the preferences with which one makes the choice. Choices about preferences are meta-choices; preferences determining meta-choices are meta-preferences.

In theory, all choices could be determined by preferences, all preferences could be meta-chosen, all meta-choices could be determined by meta-preferences, all meta-preferences could be meta-meta-chosen, all meta-meta-choices could be determined by meta-meta-preferences, &c out to any finite level of meta that you might imagine. But the levelling cannot be infinite. At some point, one reaches a level that wasn't chosen. Varieties of choices and preferences that are turtles all the way down are an impossibility. A class of choices cannot have any members if it is defined such that each member is underlain by a choice of that same class. Likewise for preferences.

And hence I come to the expression sexual preference. As introduced and still generally to-day, it refers to what one sexually prefers; it says nothing about what one meta-prefers or meta-chooses. People said to have sexual preferences are thereby said to choose with those preferences, not to have chosen the preferences themselves. Someone said to have heterosexual preferences is not thus said to have chosen heterosexuality itself, and so too of someone said to have homosexual preferences. And if we deny that sexual preferences can be real because they are not underlain by a choice of sexual orientation, then we must claim that all non-sexual preferences are likewise not real, because it's never turtles-all-the-way-down.

The only people who will be offended by the term sexual preference itself will have confused preferences with meta-preferences — or will be those people who have simply embraced the claim that the term is offensive without much thought as to why it should be so. And a rather large group will not actually be offended, but will rôle-play as if offended, because they observe that this behavior is the practice of their political tribe.

Some Common Sense about Common Sense and about Common Sense

Tuesday, 30 November 2021

I often hear or read Common sense isn't common. or, ambiguously, Common sense isn't.

The term common sense refers to variety of things believed or formerly believed to be closely related. In some cases, the term is indeed a description; in others, it is like Common Raven, which began as a description or as an attempt at a description, but names a now uncommon bird.

Consulting the SOED, I find about five definitions of common sense. Archaically, common sense refers to a supposed faculty that coördinated and united senses such as those of sight and of touch to form impressions of the world. The term may refer to ordinary or normal understanding (which must be common). Common sense may also refer to collective judgment across some group of people. Philosophers may use common sense to refer to the power by which generally accepted beliefs are formed in the absence of contemplation and of instruction. Normatively, common sense refers to reliable practical wisdom in everyday matters.

I don't use the term common sense much at all, but I occasionally use it normatively, as when I tell people that an introductory course in microeconomics will start with building-blocks of common sense but assemble them with uncommon care. Now, I suppose that I could use those very same words without normative intent, but I really am hoping that the audience will accept the blocks as themselves reliable. I cannot teach my audience everything, and I shouldn't have to teach those blocks to them.

When I use common sense normatively, the notions that I have in mind are of sound reasoning that is within the intellectual capabilities common to human beings, and of the structures of belief that result from such application. Something that would not be what I were normatively calling common sense would be unsound or outside of the possibility of common understanding. However, I'm more likely to say That should be common sense. than That seems like common sense. I'm even more likely to say That should be obvious.

I'm on the subject of common sense because various people in various groups will treat beliefs as if they are obvious to everyone who is not a fool when they are no such thing. Treating them as common sense — here using common sense normatively — is a form of implicit or explicit begging of the question; it is a violation of the rules of proper discourse. That said, most of those who treat those beliefs as common sense sincerely, thoughtlessly regard most of them as such; these people are not violating the rules willfully.

I've encountered this begging of the question by the political left, by the political right, and by political moderates. But I am at present most concerned by the misrepresentations from the left, because they have control of so much of the commanding heights of our culture. When a strong wind prevails, one leans against it, not against a wind of the past nor against a wind that may come in the distant future.

Examples of propositions that some or all of the left treat as common sense include

  • that greater economic efficiency can often be achieved by replacing markets with state administration based upon centralized collection of relevant information;
  • that material inequality is a social ill;
  • that poverty may be reduced by state-directed redistribution of wealth or of income from the affluent to those of little means;
  • that, if a school system is performing poorly, then some increase in the material resources provided to it would be sufficient to improve that performance, and that any decrease in such resources will be followed by a decline in performance.

Treating these propositions as common sense precludes consideration.

To impel consideration of all that the left distinctly takes to be common sense, we want a concise label for that group of their beliefs. We want an X such that we can say things such as This idea is X; if you're going to treat it as common sense, then you're first going to have to show that it truly is common sense. or such as This idea is X but it is not common sense; if you're going to justify it, then you're going to have to justify it on some other basis. Any label that itself begs the question, in some contrary way, will do little or nothing to promote thoughtful consideration. It will not provoke the left to think, and it will offend uncommitted members of the audience (with whom we should be principally concerned) and otherwise cause them to dismiss the argument as logomachy amongst knaves and fools. An insulting label would beg the question in an especially counter-productive way.

But the label should be used to establish a context of discourse across arguments and conversations in which context the left can no longer simply proceed with its presumptions as such or it will come to seem absurd to the audience and outmanoeuvred to itself. I don't know what the properly effective label should be.

Humpty Dumpty and Commerce

Thursday, 7 January 2021

Fairly inexpensive hair combs made of hard rubber — rubber vulcanized to a state in which it is as about firm as a modern plastic — could be found in most American drugstores at least into the mid-'90s. Now-a-days, they have become something of a premium item. I was looking at listing on Amazon supposedly of hard rubber combs and discovered, to my annoyance, that a careful reading of the descriptions showed that most of the combs explicitly described as hard rubber were made of plastic. To me, the situation seemed to be of pervasive fraud, as it will to many others.

But then I realized that it is more likely to be something else. Fraud, after all, involves deliberate misrepresentation. Whereäs we live in a world in which a great many people believe that no use of a word or phrase is objectively improper — that if they think that hard rubber means a rubbery plastic or a plastic that looks like another substance called hard rubber, then it indeed means just that. (Of course, we cannot trust any verbal explanation from them of these idiosyncratic meanings, as they may be assigning different meanings to any words with which they define other words.)

My defense of linguistic prescriptivism has for the most part been driven by concerns other than those immediate to commercial transactions. And, when I've seen things such on eBay as items described with mint condition for its age or with draped nude, my inclination has been merely to groan or to laugh. But it seems to me that the effects of ignoring or of rejecting linguistic prescription have found their way into commercial transactions beyond the casual.

Well, those who are not prescriptivists are hypocrites if they complain, and they're getting no worse than they deserve.

Science and the Humanities

Saturday, 7 November 2020

Reading a book first published in 1951, I am reminded that, at one time, the definition of humanities included sciences of human behavior within its scope. Now, one seldom encounters that inclusion in contemporary use, and the Merriam-Webster Dictionary explicitly excludes the study of social relations (though it says nothing explicit about that part of behavior outside of the social).

In the earlier period, there was a question of whether the study of human behavior were fundamentally different from the study of the properties of other things. Those who insisted upon such a difference would speak and write of science and the humanities as if of two separate things.

But the tools by which the physical, biological, and behavioral science were studied were increasingly shared. The physical and biological sciences took-up probability and statistics; the biological sciences have taken-up chemistry, mechanics, and game theory; the behavioral science have taken-up biological explanation and mathematical modelling. All have been affected by the same philosophic theories of method. A dichotomy of science and the humanities cannot prevail so long as the behavioral sciences are included amongst what are called humanities.

Apparently that dichotomy was so dear to some of those who insisted upon it that they attempted its preservation by implicitly changing what they intended with humanities in order to hold fast to it. Of course, the newer definition doesn't maintain the original dichotomy; but replaces it with a new one.

Ideas of Choice

Monday, 11 November 2019

I have been more actively working on the decision-theory paper off of which the probability paper was spun. And this effort has me thinking about the meanings of choice.

As I noted in an earlier entry to this 'blog, my paper on indecision used choice to mean no more or less than selection. I defined relations of preference in terms of choice functions, which are functions that select a subset from a set of options. Defining relations of preference in this manner seems to explain preference in terms of something called choice rather than explaining the thing called choice in terms of preference. But something called choice is often said to result from preference. Certainly, we want somehow to explain selection by persons of alternatives (even if that which explains cannot itself be observed directly!), and some notion of preference represents an attempt at explanation.

(However, if preference is the proper explanation, then preference must be very changeable; much of real-world behavior does not conform to a constant set of preferences. And people do such things as regularly selecting {A} from a set {A, B, C} yet consistently selecting {B} from a set {A, B, D}; perhaps in such cases we can still contrive an explanation in terms of preference, but we should be dubious of such explanation. I don't think that we should reject the word choice if the selections that people actually make aren't driven by preference. If preference does not provide a proper explanation, then perhaps some more general concept does. And perhaps by teasing-out what people intend by the word choice when they intend something narrower than selection, we can arrive at that generalization. That's one of the reasons that I sometimes press some people, especially fellow economists, to tell me what they intend by the word choice or by coördinate terms, when they reject its application where it seems to me to fit. I'm not trying to catch them in error or Socratically to teach a lesson to them; I'm trying to engage with them in an important investigation. But, important doubts about the use of preference in descriptive theory not withstanding, preference makes considerable sense in prescriptive use. Indeed, that sense in prescriptive use is one of the reasons that we so easily accept it in descriptive use, and even assures us that it must at least approximate a realistic description fairly well, because unreasonable behavior is costly.)

Identification of a preference is sometimes itself called choice; but sometimes preference is instead expressed in terms of whom or of what one would choose, if given the choice; and, sometimes, after a preference is expressed, the response is something such as You don't get to make that choice! In conscious identification of a preference, one selects an ideation; in reporting such an identification, one selects an utterance; and these ideations or utterances are selected in a way different from the way in which their subjects are, except in odd, self-referential cases.

In discussion of decision-making in a world of uncertainty, I've found use for an idea that I call practical choice, by which I mean selection of an option which selection causes that option to be effected with certainty.

In a world without uncertainty, there would be a simple division between what one could attain and what one could not. Preference amongst the unattainable would ex definitione be without practical significance. Discussion of preference amongst the possible would be operationally equivalent to discussion of practical choice, and rational agents would always attain that possible state-of-the-world that they most desired.

When we begin to speak and write of uncertainty, we are actually speaking and writing of cases in which we may make practical choices amongst options that would, in turn, affect the state-of-the-world in imperfectly predictable ways. Hypothetically, I might not care about those effects; I might only care about the options that I can practically choose; but, with those options properly identified, that hypothetical is highly implausible and sterile. And, otherwise, it now becomes quite relevant to consider the difference and relationship between preferences amongst things that are subject to practical choice and preferences amongst things that are not subject to practical choice. Preferences amongst things that an agent cannot practically choose will determine preferences amongst things that she can.

(Our practical choices are more limited than some might at first realize. An agent has practical choice of no more than some mental states; and selecting amongst these mental states delivers no more power over other possibilities than to increase or decrease the probabilities of those possibilities. Given the selection of one mental state, one's arm is more likely to move, but there is at least some terrible possibility that it will not. Indeed, given the selection of one mental state, one is more likely to recall a desired datum, but there is a possibility that one will not. Still, in many cases we might, without doing too much violence to realism, pretend that our practical choices include operations that we think almost surely to follow upon our exercise of actual practical choice. For example, one might calculate as if one had a practical choice of whether to propose marriage, while acknowledging that one did not have a practical choice over whether one would marry the other party.)

The concern of my paper on indecision was in identifying a difference in observable behavior distinguishing indecision from indifference, and I didn't want that distinction to be simply self-reported. When an agent was undecided between X and Y rather than indifferent, I needed a difference in selection from a set in which X and Y options, rather than a difference in selection amongst utterances or somesuch. In hindsight, I wish that, in that paper, I'd discussed conceptions of choice more than I did, and had explicitly written of practical choice. Perhaps accordingly I will someday revise the working version of the paper.

Sowing Pseudo-Scientific Seeds of Racism

Thursday, 2 August 2018

I have previously expressed great concern about journalists confusing the categorization of a people as H. sapiens with their being human. Bodies Keep Shrinking on this Island, and Scientists Aren't Sure Why, a story in the New York Times, offers yet another illustration of this confusion. Within it, Carl Zimmer writes:

The researchers found that a very small percentage of the villagers' DNA came from Neanderthals or Denisovans. A tiny portion could not be matched to humans, Neanderthals or Denisovans.

But these enigmatic pieces weren’t dramatically different from human DNA, as you’d expect if they had come from Homo floresiensis. Dr. Tucci concluded that the Rampasasa villagers have no Homo floresiensis ancestry.

Note that, once again, Neanderthals and Denisovans are distinguished by a journalist from humans, as are now those of H. floresiensis. No reason is given for classifying any of these people as not human; the journalist has simply inferred that they are not because they have been classified as of a different species; what that classification actually means is utterly unconsidered.

Further, in the article, modern populations are noted to have differing occurrences of presence of DNA from the supposedly inhuman populations — not dramatically inhuman, but supposedly inhuman none-the-less.

Let me make it very plain: Mr Zimmer and the New York Times are offering pseudo-science with racist implications. He probably doesn't intend those implications, but is simply thoughtless. However, his thoughtlessness and that of his editors are inexcusable. And, if he had any conversations with the scientists who conducted these studies, then I'd like to know why the Hell they failed to impress upon him that the taxonomy did not separate people into humans and non-humans. These scientists did not have the prerogative of unscientifically presuming that Mr Zimmer had more intelligence than has been actually demonstrated by the typical journalist.

On the Meaning of Sexism

Thursday, 11 May 2017

In a previous entry, I noted that the original definition of racism was a theory or an adherence to a theory that merit is in part intrinsically a function of race. It was exactly by analogy with the word racism that the word sexism was introduced in 1968, thus referring to a theory or an adherence to a theory that merit is in part intrinsically a function of sex.

Now, here is where matters get tricky. In any case in which one rejects sexism, it is regarded as an inappropriate response to the sex of people; and, in particular, the treatment is likely to be seen as unethical. A very great many folk employ the concept of unethical response to the sex of people as if that were the very definition of sexism. That notion is going to operationalize very much like the actual definition whenever and wherever the issue at hand is one of ethics and ethics actually call for neutrality — for a rejection of the relevance of sex to the issue. But nearly all of us regard people of one sex as better suited to some rôles that are of importance. For example, if I presume that sexism must refer to something unethical, then I am compelled either to associate sexism with something other than neutrality of a sort, or as a matter of justice to try to entertain thoughts of accepting a man as a potential spouse for myself. (People are led astray by the analogy with racism; the cases in which sex is relevant to selection loom larger because of the importance of reproduction.) And the substituted notion is not going to operationalize at all like the original definition exactly when someone believes that merit is a function of sex in a far wider range of cases than do folk such as I; then the substitution is going to get things almost perfectly twisted around. He or she will label anti-sexism as sexism and will label some sort of sexism — perhaps quite an intense sexism — as anti-sexism.

The spurning of a claim of relevance is the maintenance or adoption of indifference. This indifference is an equality of one sort — and we often see the words equal and equality used in antonymy to sexism — but it is not an equality of various other sorts. Advancement of a conflicting equality would itself be sexist. Such conflicting equalities can arise when the equality sought is equality of outcome. If people, regardless of sex, may be presumed to respond to a framework in essentially identical ways, and we observe markèdly different outcomes for one sex compared to those for another, then this difference is prima facie evidence that the framework is sexist. But if it is recognized that people of one sex behave differently in that framework, then the presumption that the framework is sexist does not follow from the mere presence of a difference. If we say that the different behaviors must be treated as of equal merit because otherwise a difference in outcomes emerges, then the merit that is ascribed to the behavior is treated as a function of the sex of the people who engage in that behavior; that prescription is itself intrinsically sexist.

For example, the rates at which men are arrested for, charged with, and convicted of criminal behavior of various sorts are much higher than the corresponding rates at which women are arrested, charged, and convicted. We cannot conclude simply from these differences that the system of criminal law is sexist, because it may be that men simply engage in that behavior more often; indeed, most of us are fairly sure that this latter case holds. If we insist that the behaviors themselves must be decriminalized in order to reduce the rates at which men are arrested, charged, and convicted, then we are inferring the relative merit of the behavior from the sexes of those who engage in it. The very same sort of analysis would apply to hiring practices and to the wages or salaries paid to those in various occupations.[1]

(Many people, including certainly me, would argue that an unfortunate sexism prior to whatever exists in the legal system is one factor contributing to greater criminality by men, but few-if-any people propose that part of an appropriate response would be an adjustive sexism, giving more tolerance to male criminalized behavior than to female criminalized behavior. Likewise, some of us assert that an unfortunate sexism prior to whatever exists in the jobs market is one factor leading to different career outcomes for women, but we don't propose an adjustive sexism attempting to compel employers to pay women more than the expected values of their marginal products.)

The confused presumptions that only an unethical discrimination can count as sexism and that sexism is found where there is some sort of inequality other than non-neutralityan attention to sex — causes people in all sincerity to misapply the word sexism and to fail to see legitimate application of the word, perhaps to their own attitudes and actions. If substitutions of these sorts are not recognized by those who use the word sexism in accordance with its definition, then interactions will be characterized by mutual incomprehension, quite possibly enraged. Attempts to employ logic and facts won't be persuasive because one of the two groups will actively misunderstand a word central to any communication. Additionally, there are people who implicitly believe that ethical significance clings to symbols, such that by changing labels what was wrong may be made to be right and vice versa. In dealing with them, the principal point that ought to be made is not that words cannot be redefined, but that, if we should for any reason redefine sexism, then whatever case was made against what was originally called sexism isn't thereby logomantically transformed into a case against whatever is now to be called sexism, nor is a case against something that was originally called sexism somehow invalidated by ceasing to call it by that name.[2] Of course, there are also those who effect the substitution as a device of unconscious projection, and others who opportunistically seek to sow further confusion.


[1] In the absence of a coherent explanation otherwise, if any population really could be hired at bargain rates, then not only should we expect all members of that population to be hired before any members of any other population; we should expect employers to bid-up the wages and salaries of this less expensive population to the point that they matched those of other populations, before hiring any members of those other populations. If there is some occupation such that the cost of hiring workers for it is notably less than the expected values of their marginal products, then we should expect employers to increase their hirings for those occupations, and in doing so (each in competition with the others and in the face of otherwise ever more reluctant workers) to bid-up the wages or salaries of those workers until the difference disappears.

[2] The same principle of course applies to efforts to redefine racism.

λέγει αὐτῷ ὁ Πιλᾶτος τί ἐστιν ἀλήθεια;

Wednesday, 25 January 2017

Years ago, National Lampoon had a monthly column that they entitled True Facts. The title was a joke, not because the contents weren't true (they were an assembly of extraödinary news reports), but because facts cannot be untrue; something untrue is not a fact. Yet many people in various contexts were using terms such as actual fact, real fact, and true fact, almost as if it were possible for some facts to be false, imaginary, unreal. People still do, perhaps even more often. One can find lots of instances of people using imaginary fact; sometimes they do so ironically, but more often they are quite serious. By imaginary fact they mean a proposition that may be untrue, is likely to be untrue, or simply is untrue. In this retasking of the word fact, they've lost the use of the word to talk about facts, unless they add a word such as true. But, with that change in meaning, it not only becomes possible to use a term such as alternative fact to refer to a rival claim, but it becomes harder to see that untrue rival claims don't have equal standing with true rival claims, as they are all supposedly facts.

We aren't at all helped here that a great many people don't understand the words true and truth. That's not simply a problem of vocabulary. Truth is a hard concept, because it entails a meta-propositional act of mapping from a proposition back to itself. That is to say that, in most cases when we apply the word true or equivalent and certainly in the case of true facts, we are explicitly or implicitly making a proposition about a proposition. When we say It's true that I went to the store, that actual referent of the grammatic subject is not I, but the proposition that I went to the store, yet the upshot of this sentence is merely what would be conveyed in saying I went to the store. We perhaps don't need this device of recasting a proposition (I went to the store) as a meta-proposition (It is true that I went to the store), but it is useful because we are not omniscient, and must entertain propositions that are uncertain or discovered to be false; the concept of truth complements the conditions of falsehood and of uncertainty. Yet it is very hard to see that function, exactly because we use the concept to discuss itself. Truth is more easily named than described, if indeed a description is possible.

The difficulty in understanding the nature of truth makes it psychologically easier to embrace such notions as that all aspects of of past, present, and future are simply artefacts of individual belief or of group belief (expressed with formulæ such as truth is a social construct) or that what one wants or ought to want is to be treated a true. The word fact may then be used for components of narratives; embracing one narrative is seen as licensing one to accept propositions as fact that are alternative to components of rival narratives, and to reject propositions for no better reason than that they participate in rival narratives. Evolution of narratives is seen as licensing one to change the status of a proposition from fact to falsehood, or vice versa, even when discussing history. And we may even observe those socially identified as fact-checkers testing claims against narratives which are themselves never fact-checked, because the checkers implictly treat their favored narratives as the ultimate determinant of fact.

When Pilate asked What is truth?, perhaps he was truly curious as to the nature of truth, but he may merely have been asking why he should give a damn about it. Our political leaders have become ever more disdainful of truth. They have long offered us alternative facts, and their followers in each of our major political tribes and in most of the smaller groups as well have decided that, for them, these are the facts. Now we have an Administration that does so more baldly and less artfully. One might hope that this practice will explode on them; but, even if that explosion should happen, their opponents are likely to see an expansion of the envelope within which they may disregard the facts.

Recognizing the Difference

Tuesday, 17 January 2017

The word problem is used for multiple concepts:

  • a challenge, especially a mental challenge
  • an unhappy state of affairs that exercises the mind
  • a seemingly insurmountable difficulty

These may actually be very different things, because some states-of-affairs may be changed, and some may not; but it is often hard to distinguish the former from the latter. Thence we use the same word for all three concepts, and thence we get the famous Serenity Prayer of Reinhold Niebuhr:

God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.

A good economist is going to note that sometimes the costs of changing what we can would be higher than the benefit. Properly understood, that greater costs would mean that we were trading some greater problem for a solution to the problem under immediate consideration. The Serenity Prayer might lead one to mistake sensible calculation for cowardice, though poetry might have to be sacrificed to provide better guidance.

Still, the distinction between that which we can change and that which we cannot is most fundamental, and confusion between the two is a source of frustration and of anguish. That which displeases us and which we can change is a challenge about which we can usefully exercise the mind, until such time as either we develop a reasonable method of changing things or we recognize that it's not worth the cost. That which displeases us and which we cannot change is an unhappy condition of existence; and — ideally — we ought to come to terms with that condition, to accept it, so that it no longer exercises our minds. (And we ought, similarly, to accept those states the changing of which, though possible, truly would be too costly.)

One seldom-noted root of some of the confusion is a failure to distinguish between what the person in question may change and what someone else may change. The state-of-affairs might be a problem for a person who could change it, or it might not be a problem for that person; but, either way, by someone who cannot change it, it is best treated as a condition of existence.

It may be especially hard to see the distinction when the other person might indeed act to change things and, if that other person did, the first person would want to undertake quickly some course of action. But, likewise, there might be some potential event which would have to be impersonally caused (if at all) and which would call for a prompt response. One should not try to cause that which no person can cause, and one should not try to cause that which only another person can cause, even if there would be things to do should it happen.

It may be too much to hope for serenity from such realizations. It is certainly too much to demand that others be serene in the face of indifference, indecision, or madness on the part of those around them. Sometimes grim acceptance is the best that one can manage.
